Answer:
Hey there!
Gold would have a greater mass, because density is mass/volume, and if the density is greater, so is the mass.
Let me know if this helps :)
Answer: At
Transition state <span>stage of a reaction do atoms have the highest energy.
Explanation:
In a chemical reactions reactants reacts to produce products. Reactants have their specific energies and products have their own. If energy of reactants is greater than that of products then it is
exothermic reaction, or if it is less than that of products then it is
endothermic reaction.
When reactants approaches each other in order to react their old bonds start breaking and new bonds start forming. This stage of
partial bonds is called as
Transition state. Transition state has very
high energy as compared to energies of reactants and products. Therefore, due to its high energy it is very
unstable and exists for a very short period of time and converts into products.</span>
Answer: The blue and white golf balls; they have more mass than the yellow golf ball, but changed speed by the same amount.
Explanation:
<span>If less than 1% of ethanoic acid is ionized in an instant, ethanoic acid is considered a weak acid.
Ethanoic (acetic) acid ionization: CH</span>₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
In water ethanoic acid is mainly in CH₃COOH form, only 1% in CH₃COOH and H⁺ ions, because it gives little hydrogen ions, this acid is <span>considered weak monoprotic acid.
</span>In aqueous solution, acetic acid has a <span>pKa</span><span> value of 4.76.</span>
Answer:
0.75 mol
Explanation:
concentration=mole/volume
c×v=n
volume=2.50l=2.50dm³
0.300×2.50=0.75mol
